I don't write to solr, but I do query it (and writing should work equivalently).
My route for querying is just:
<route id="SolrQuery">
<from uri="direct:solrQuery" />
<setHeader headerName="CamelHttpQuery">
<simple>${body}</simple>
</setHeader>
<to uri="http://server:8983/solr/test/select/?disableStreamCache=true"; />
<convertBodyTo type="java.lang.String" />
<unmarshal ref="solrToMap"/>
</route>
That route takes in the query string for solr as the body and then returns the
data from solr as a map.
You might find it simpler to ignore java code for calling solr, and just talk
http to it.
